Neodymium magnets exist

Magnetized and Real Attributes
Numerous grades of Neodymium magnets exist to support many different industrial programs. The range of Neo grades usually expands from 33 MGOe to 52 MGOe. This range enables optimizing cost, overall performance, and functional temperature weight.

The normal meeting for “Grade” is to use the value of certain magnet alloy’s Energy Density or optimal Energy item. Frequently, you can find letters or a two digit number suffix connected to the Grade which suggests the Intrinsic Coercive Force (Hci) standard of the magnet alloy. This Hci is a great indicator of maximum allowable temperature a specific Neo alloy can tolerate before permanent demagnetizing occurs.

The higher the “Grade number,” the higher the power Density. Frequently, the greater the Energy Density, the more powerful the magnet, but this can be very much based mostly on the magnet’s operational environment.

* optimum working Temperature for this Group is 230°C / 446°F ( L/D ≥0.7)
